After reading the accompanying background information, students create an ice core using a tennis ball container and an assortment of dyes and craft supplies. Students measure the thickness and determine the age of each layer. As an extension...(View More) activity, students write a story about their ice core.(View Less)

Acting as the ICESat-2 satellite, students investigate the reflection of light photons off Earth's surface by catching and recording a number of photons. Using bouncy balls to represent the photons, students drop, let bounce once and try to catch in...(View More) one hand as many balls (photons) as possible. Drops occur on carpeted and non-carpeted areas, and with and without the presence of cardboard buildings, to represent different Earth surfaces. The lesson includes background information, instructions and concluding questions. Related Next Generation Science Standards (NGSS) are listed.(View Less)

Using water to represent the atmosphere and milk droplets to represent aerosols, students make predictions and conduct investigations to discover how different aerosol concentrations affect atmospheric color and visibility. This lesson is one of...(View More) four in the GLOBE program storybook entitled, "What's Up in the Atmosphere? Exploring Colors in the Sky." GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program.(View Less)

Through the use of prisms and glue sticks, this activity introduces students to a fundamental property of light: white light is made up of colors representing different wavelengths. Students use the results of the activity to explain the variation...(View More) in sky color from daytime (blue) to sunset (red). This lesson is one of four in the GLOBE program storybook entitled, "What's Up in the Atmosphere? Exploring Colors in the Sky." GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program.(View Less)

Working in groups, students use contact paper to make samplers to collect local data on aerosols - the small particles found in the atmosphere. Students then analyze, interpret and make predictions based on their data. Both the instructions for...(View More) making the aerosol sampler and the data sheets are included. This lesson is one of four in the Elementary GLOBE storybook entitled, "What's Up in the Atmosphere? Exploring Colors in the Sky." GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program.(View Less)

This unit consists of four activities. Students begin by examining temperature cycles (current, recent and historical) then add in factors such as carbon dioxide, precipitation and cloud cover to discover regional and global differences in the...(View More) effects of climate change. The unit is one of four under the Chicago Botanic Garden curriculum entitled, "Climate Change in My Backyard."(View Less)

Students are introduced to the carbon cycle through discussion, modeling and a game. Students then complete activities and investigations on Greenhouse gasses, photosynthesis, cellular respiration and ecosystem services (functions and values of...(View More) intact ecosystems to humans). The unit is one of four under the Chicago Botanic Garden curriculum entitled, "Climate Change in My Backyard."(View Less)

This unit consists of two parts, each with several activities which require students to participate in investigations, discussions, computer data analysis, role-playing, and research. In Part 1, students examine the roles of Earth's energy balance...(View More) and the greenhouse effect in creating and affecting climate. Part 2 focuses on the biosphere as a system. Students examine the interactions of organisms, the effects of climate change on food webs, and the importance to humans of a healthy, intact ecosystem. The unit is one of four under the Chicago Botanic Garden curriculum entitled, "Climate Change in My Backyard."(View Less)

Common materials such as sand, gravel, pebbles, shells, etc. are used to represent crustal materials from an unknown planet. Students begin by sorting, classifying, and making observations about the sample. Using that information, they must then...(View More) interpret the geologic and biologic history of the planet. The lesson is part of the Mars Educxation Program series; it models scientific inquiry using the 5E instructional model and includes teacher notes and vocabulary. Next Generation Science Standards are listed.(View Less)

This activity demonstrates optical properties of water: that different constituents in water affect the transmission, absorption, and scattering of different colors in the visible light spectrum. Inexpensive, off-the-shelf components are used to...(View More) build a light sensor and source, creating a simple spectrophotometer that can measure light absorption. In the second part of this activity, principles of ocean color remote sensing are applied to measure reflectance. Using components that are clearly visible allows students to configure them in different ways. Playing with the instrument design gives students a practical understanding of spectrophotometers, in-water optics, and remote sensing. As an extension of this concept, students are encouraged to think about how ocean color is used to estimate the concentration of chlorophyll to infer phytoplankton abundance, colored dissolved organic matter, and suspended sediments.(View Less)
